I am the new owner of a Lola T-590 (HU-6). It has been parked for at least 9 years, so I am going through it. I have run across an issue that I cannot find an answer for. Were buck rivets used exclusivly or did they also use some pop rivets? I cannot figure out how they got access to some areas..... If so do you know how?

Would like every aspect of the car to be as correct as possible 1980-85 period corrrect.

Any and all help is appreciated.

In this photo my car has both, when most of them could be Bucks rivets.....which are better by design.
